Mains electricity is alternating current supplied at a frequency of 50 or 60 cycles per second.
A power inverter can make the conversion to AC, but a typical inverter with the required capabilities contains about 300 pounds of material: a computer to change the frequency of alternating current as motor speed changes, massive switches, and cooling equipment to dissipate the heat generated by the heavy current.
Whole - body resistance and reactance were measured with the patient lying supine on a nonconductive surface with the use of a phase - sensitive, single - frequency impedance plethysmograph [400 - μA, 50 - kHz alternating current (BIA - 101; RJL / Akern Systems)-RSB-.

Radio waves are actually just a high frequency type of alternating current (AC), which is the type of electricity in our power grids, but devices need DC power to operate.
And they did not address the difficulties of maintaining voltage and frequency of alternating current within extremely tight limits (a necessity in technologically dependent societies) when a large share of the supply is from wind and solar.
